Sulphur Tuft (Hypholoma fasciculare)

Our dead whitebeam stump wears a spectacular golden cape this autumn – a mass of Sulphur Tuft (Hypholoma fasciculare) mushrooms which spill down its side and extend out along its roots. At first, they had the rounded tops of the tiny one in the foreground but they soon flattened out, though often retaining a little raised bump in the centre. They're smooth on top, typically yellowish on the edges and darker orangey-tan in the middle. Their stalk (called the stipe by those who study fungi) is also two-toned: yellow near the cap and darker at the base. The gills, which are the thin ribs located on the underside the cap, are attached to the stipe, an arrangement which can be an important ID feature. The gills start yellowish-green, like those in the photo above, and go darker with age.

Sulphur Tufts are very common and widespread in the UK, and across much of Europe and North America as well. They attack the dead, decaying wood of both coniferous and deciduous trees, like that of our poor whitebeam, which succumbed to a windstorm several years ago. Rumour has it that they taste bitter. Given that consumption causes serious gastrointestinal issues, I don't think I'll be checking that out in person!
